Medullary thyroid carcinoma with multiple hepatic metastases: treatment with transcatheter arterial embolization and percutaneous ethanol injection. (1/892)

A 54-year-old man with medullary thyroid carcinoma in the thyroid gland was unable to undergo total thyroidectomy because the tumor had invaded the mediastinum. Radiation therapy and chemotherapy were given. Seven years later, intractable diarrhea and abdominal pain appeared, and computed tomography demonstrated hypervascular tumors in the thyroid gland and in the liver. The tumors were successfully treated with percutaneous ethanol injection to a lesion in the thyroid gland and transcatheter arterial embolization followed by percutaneous ethanol injection to tumors in the liver. Transcatheter arterial embolization and percutaneous ethanol injection may be valuable in treating medullary thyroid carcinoma.  (+info)

Modulation of cell proliferation and differentiation through substrate-dependent changes in fibronectin conformation. (2/892)

Integrin-mediated cell adhesion to extracellular matrices provides signals essential for cell cycle progression and differentiation. We demonstrate that substrate-dependent changes in the conformation of adsorbed fibronectin (Fn) modulated integrin binding and controlled switching between proliferation and differentiation. Adsorption of Fn onto bacterial polystyrene (B), tissue culture polystyrene (T), and collagen (C) resulted in differences in Fn conformation as indicated by antibody binding. Using a biochemical method to quantify bound integrins in cultured cells, we found that differences in Fn conformation altered the quantity of bound alpha5 and beta1 integrin subunits but not alphav or beta3. C2C12 myoblasts grown on these Fn-coated substrates proliferated to different levels (B > T > C). Immunostaining for muscle-specific myosin revealed minimal differentiation on B, significant levels on T, and extensive differentiation on C. Differentiation required binding to the RGD cell binding site in Fn and was blocked by antibodies specific for this site. Switching between proliferation and differentiation was controlled by the levels of alpha5beta1 integrin bound to Fn, and differentiation was inhibited by anti-alpha5, but not anti-alphav, antibodies, suggesting distinct integrin-mediated signaling pathways. Control of cell proliferation and differentiation through conformational changes in extracellular matrix proteins represents a versatile mechanism to elicit specific cellular responses for biological and biotechnological applications.  (+info)

Can vector control play a useful supplementary role against bancroftian filariasis? (3/892)

A single campaign of mass treatment for bancroftian filariasis with diethylcarbamazine (DEC) in Makunduchi, a town in Zanzibar, United Republic of Tanzania, combined with elimination of mosquito breeding in pit latrines with polystyrene beads was followed by a progressive decline over a 5-year period in the microfilarial rate from 49% to 3%. Evidence that vector control had contributed to this long-term decline was obtained by comparison with another town, Moga, where a DEC campaign was used without vector control and where resurgence of microfilariae could be observed 3-6 years after the campaign. In Zanzibar town, treatment of 3844 wet pit latrines and cesspits with polystyrene beads reduced the adult mosquito population in houses by about 65%. Supplementary treatment of open drains and marshes with Bacillus sphaericus produced little or no additional reduction compared to a sector of the town where only pit treatment with polystyrene was carried out. The cost and effort of achieving the 65% reduction in mosquito population could hardly be justified for its impact on filariasis alone, but its noticeable impact on biting nuisance might help to gain community support for an integrated programme.  (+info)

Defensins impair phagocytic killing by neutrophils in biomaterial-related infection. (4/892)

The implantation of foreign material carries a risk of infection which frequently is resistant to all treatment short of removing the implant. We have previously shown that these materials activate neutrophils by contact, leading to production of oxygen free radicals accompanied by release of granule products. Such activation further results in depletion of local host defenses, including the capacity of biomaterial-activated neutrophils to kill bacteria. Among the granule products released from neutrophils are small cationic antibacterial peptides (human neutrophil peptides [HNP]) known as defensins. Here we tested the hypothesis that defensins, released from activated neutrophils onto the surface of biomaterials, might play a role in the deactivation of subsequent neutrophil populations. Incubation of neutrophils with purified HNP resulted in a dose-related impairment of stimulus-induced oxygen radical production and of phagocytic killing. Furthermore, fresh neutrophils added to biomaterial-associated neutrophils exhibited impaired phagocytic killing. This impairment could be abrogated by antibody to HNP but not by an irrelevant antibody. Taken together, these observations support the idea that neutrophils activated at a material surface can create, by means of HNP release, an environment hostile to their microbicidal function and that of their infiltrating brethren.  (+info)

Quantitative analysis of styrene monomer in polystyrene and foods including some preliminary studies of the uptake and pharmacodynamics of the monomer in rats. (5/892)

A variety of food containers, drinking cups and cutlery, fabricated from polystyrene (PS) or polystyrene-related plastic, were analyzed for their styrene monomer content. Samples of yogurt, packaged in PS cups, were similarly analyzed and the leaching of styrene monomer from PS containers by some food simulants was also determined. Blood level studies with rats, dosed with styrene monomer by various routes, illustrated uptake phenomena that were dependent on the dose and route of administration and were also affected by the vehicle used to convey the styrene monomer.  (+info)

Protein adhesion force dynamics and single adhesion events. (6/892)

Using the manipulation force microscope, a novel atomic force microscope, the adhesion forces of bovine serum albumin, myoglobin, ferritin, and lysozyme proteins to glass and polystyrene substrates were characterized by following the force necessary to displace an adsorbed protein-covered microsphere over several orders of magnitude in time. This force was consistent with a power law with exponent a = 0.37 +/- 0.03 on polystyrene, indicating that there is no typical time scale for adhesion on this substrate. On glass, the rate of adhesion depended strongly on protein charge. Forces corresponding to single protein adhesion events were identified. The typical rupture force of a single lysozyme, ferritin, bovine serum albumin, and myoglobin protein adhering to glass was estimated to be 90 +/- 10 pN, 115 +/- 13 pN, 277 +/- 44 pN, and 277 +/- 44 pN, respectively, using a model of the experimental system. These forces, as well as the force amplitudes on hydrophobic polystyrene, correlate with protein stiffness.  (+info)

RecA polymerization on double-stranded DNA by using single-molecule manipulation: the role of ATP hydrolysis. (7/892)

The polymerization of RecA on individual double-stranded DNA molecules is studied. A linear DNA (lambda DNA, 48.5 Kb), anchored at one end to a cover glass and at the other end to an optically trapped 3-micrometers diameter polystyrene bead, serves as a template. The elongation caused by RecA assembly is measured in the presence of ATP and ATP[gammaS]. By using force extension and hydrodynamic recoil, a value of the persistence length of the RecA-DNA complex is obtained. In the presence of ATP, the polymer length is unstable, first growing to saturation and then decreasing. This suggests a transient dynamics of association and dissociation for RecA on a double-stranded DNA, the process being controlled by ATP hydrolysis. Part of this dynamics is suppressed in the presence of ATP[gammaS], leading to a stabilized RecA-DNA complex. A one-dimensional nucleation and growth model is presented that may account for the protein assembly.  (+info)

Spore surface glycoproteins of Colletotrichum lindemuthianum are recognized by a monoclonal antibody which inhibits adhesion to polystyrene. (8/892)

Conidia (spores) of Colletotrichum lindemuthianum, a fungal plant pathogen causing bean anthracnose, adhere to the aerial parts of host plants to initiate the infection process. These spores possess a fibrillar 'spore coat' as well as a cell wall. In a previous study a mAb, UB20, was raised that recognized glycoproteins on the spore surface. In this study UB20 was used to localize and characterize these glycoproteins and to investigate their possible role in adhesion. Glycoproteins recognized by UB20 were concentrated on the outer surface of the spore coat and, to a lesser extent, at the plasma membrane/cell wall interface. Extraction of spores with hot water or 0.2% SDS resulted in removal of the spore coat. Western blotting with UB20 showed that a relatively small number of glycoproteins were extracted by these procedures, including a major component at 110 kDa. Biotinylation of carbohydrate moieties, together with cell fractionation, confirmed that these glycoproteins were exposed at the surface of the spores. In adhesion assays, > 90% of ungerminated conidia attached to polystyrene Petri dishes within 30 min. UB20 IgG at low concentrations inhibited attachment in an antigen-specific manner. This suggests that the glycoproteins recognized by this mAb may function in the initial rapid attachment of conidia to hydrophobic substrata. Polystyrene microspheres bound selectively to the 110 kDa glycoprotein in Western blots, providing further evidence that this component could mediate interactions with hydrophobic substrata.  (+info)

Sodium polystyrene sulfonate is a non-absorbed, cation exchange polymer that contains a sodium counterion.. Sodium polystyrene sulfonate increases fecal potassium excretion through binding of potassium in the lumen of the gastrointestinal tract. Binding of potassium reduces the concentration of free potassium in the gastrointestinal lumen, resulting in a reduction of serum potassium levels. The practical exchange ratio is 1 mEq K per 1 gram of resin.. As the resin passes along the intestine or is retained in the colon after administration by enema, the sodium ions are partially released and are replaced by potassium ions. This action occurs primarily in the large intestine, which excretes potassium ions to a greater degree than does the small intestine. The efficiency of this process is limited and unpredictably variable.. ...

Polystyrene sulfonates are polymers derived from polystyrene by the addition of sulfonate functional groups. They are widely used as ion-exchange resins to remove ions such as potassium, calcium, and sodium from solutions in technical or medical applications. Linear ionic polymers are generally water-soluble, whereas cross-linked materials (called resins) do not dissolve in water. These polymers are classified as polysalts and ionomers. Polystyrene sulfonate is usually supplied in either the sodium or calcium form. It is used as a potassium binder in acute and chronic kidney disease for people with hyperkalemia (abnormal high blood serum potassium levels). However, it is unclear if it is medically beneficial and there is concern about possible side effects when it is combined with sorbitol. Polystyrene sulfonates are given by mouth with a meal or rectally by retention enema. Under the name tolevamer, a polystyrene sulfonate was investigated by Genzyme as a toxin binding agent for the treatment ...
Autori: V. Neagu, I. Untea, E. Tudorache et C. Orbeci. Editorial: Revue Roumaine de Chimie, 52 (4), p.433-437, 2007.. Rezumat:. In this study, comparative experimental data regarding the equilibrium of phenol retention in water solutions through adsorption on synthesized (S-DVB) and commercial (Amberlite XAD-1) macroporous styrene - divinylbenzene copolymers, with different morphological structures are presented. The phenol adsorption capacity of water solution, expressed under the form of isotherms of adsorption is found to be in a positive correlation with the structural and morphological properties of macroporous copolymers, especially with their specified surface. The values of the adsorption capacity are highly influenced by concentration, the experimental isotherms of adsorption being related to the Freundlich - type isotherm. The previous swelling of macroporous styrene-divinylbenzene copolymers in contact with methyl alcohol leads to a great increase (of 50-100%) in the retention ...

The optimum conditions for preparing and the performance of a high efficiency polymeric column were compared with those of micro-particle-filled capillary columns, including a totally porous silica C18 column and a HALO® fused core C18 column. Tryptic peptides were used as model compounds for evaluating the performance of three in-house fabricated columns. After optimization, a monolithic capillary column was prepared by the in situ polymerization of styrene and divinylbenzene (PS-DVB) within a 50 μm i.d. fused silica capillary using 1-propanol as the porogen. ...
TY - JOUR. T1 - Electronic properties of hybridized poly (3, 4-ethylenedioxythiophene). T2 - Polystyrene sulfonate with surface-capped CdSe nanocrystals. AU - Wang, Seok Joo. AU - Park, Hyung Ho. PY - 2009/2/9. Y1 - 2009/2/9. N2 - The chemical state and electronic properties of hybrid material based on poly (3, 4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS) and pyridine-capped CdSe nanocrystals have been investigated using photoemission spectroscopy, near-edge x-ray absorption fine structure, and ultraviolet photoelectron spectroscopy. With a high dipole moment as well as high physical momentum, CdSe nanocrystals hindered the rearrangement of PEDOT:PSS and induced PSS-rich surface during film formation. Thus, the work function value was decreased by dedoping of PEDOT or charge localization in PEDOT. Through heat treatment, the behavior of π - π transition in C 1s and the work function value was nearly restored, gradually; these mean recovery of electrostatic bonding nature ...

The interaction between nanoparticles and cells has been studied extensively, but most research has focused on the effect of various nanoparticle characteristics, such as size, morphology, and surface charge, on the cellular uptake of nanoparticles. In contrast, there have been very few studies to assess the influence of cellular factors, such as growth factor responses, on the cellular uptake efficiency of nanoparticles. The aim of this study was to clarify the effects of epidermal growth factor (EGF) on the uptake efficiency of polystyrene nanoparticles (PS NPs) by A431 cells, a human carcinoma epithelial cell line. The results showed that EGF enhanced the uptake efficiency of A431 cells for PS NPs. In addition, inhibition and localization studies of PS NPs and EGF receptors (EGFRs) indicated that cellular uptake of PS NPs is related to the binding of EGF-EGFR complex and PS NPs. Different pathways are used to enter the cells depending on the presence or absence of EGF. In the presence of EGF,

Sanitation determined polystyrene foam products were unrecyclable. Sanitation Commissioner Kathryn Garcias decision that expanded polystyrene cannot be recycled has been upheld by the Appellate Division. The decision paves the way for the City to ban the use of expanded polystyrene single service articles.. Expanded polystyrene is a plastic resin manufactured into consumer products such as foam cups, containers, trays, plates, clamshell cases, and egg cartons. On January 2015, the de Blasio Administration announced that food service establishments, stores, and manufacturers were banned from possessing, selling, or offering for use single service expanded polystyrene foam articles and polystyrene loose fill packaging starting July 2015. Sanitation determined that expanded polystyrene foam could not be recycled and that there was no current market for a post-consumer collection of the expanded polystyrene foam. The determination was made after considering environmental effectiveness, economic ...
We demonstrate resonance optical trapping of individual dye-doped polystyrene particles with blue- and red-detuned lasers whose energy are higher and lower compared to electronic transition of the dye molecules, respectively. Through the measurement on how long individual particles are trapped at the focus, we here show that immobilization time of dye-doped particles becomes longer than that of bare ones. We directly confirm that the immobilization time of dye-doped particles trapped by the blue-detuned laser becomes longer than that by the red-detuned one. These findings are well interpreted by our previous theoretical proposal based on nonlinear optical response under intense laser field. It is discussed that the present result is an important step toward efficient and selective manipulation of molecules, quantum dots, nanoparticles, and various nanomaterials based on their quantum mechanical properties.. © 2017 Optical Society of America.

BACKGROUND: carbon nanotubes (CNT) can have adverse effects on health. Therefore, minimizing the risk associated with CNT exposure is of crucial importance. The aim of this work was to evaluate if coating multi-walled CNT (MWCNT) with polymers could modify their toxicity, thus representing a useful strategy to decrease adverse health effects of CNT. We used industrially-produced MWCNT uncoated (NT1) or coated (50/50 wt%) with acid-based (NT2) or polystyrene-based (NT3) polymer, and exposed murine macrophages (RAW 264.7 cell line) or Balb/c mice by intratracheal administration. Biological experiments were performed both in vitro and in vivo, examining time- and dose-dependent effects of CNT, in terms of cytotoxicity, expression of genes and proteins related to oxidative stress, inflammation and tissue remodeling, cell and lung tissue morphology (optical and transmission electron microscopy), and bronchoalveolar lavage fluid content analysis. RESULTS: extensive physico-chemical characterization of MWCNT

Resins produced by our process are chemically defined, homogeneous and free from any additional crosslinking from the functionalization process. Aminomethylated polystyrene resins can easily be acylated with any appropriate carboxylic acid-containing linker using standard methods of amide bond formation to furnish supports for solid phase organic synthesis. ...
Questions arose around the WMEAC office recently about recycling expanded polystyrene, also known as Styrofoam or EPS, via the City of Grand Rapids single stream recycling service. The confusion came about because Styrofoam is one of the items the city explicitly prohibits residents putting in their curbside recycling bins, even though plastic polymers 1-7 are accepted, including polystyrene (#6).. Non-expanded polystyrene is used in a variety of items: protective packaging like CD and DVD cases, laboratory equipment like petri dishes and test tubes, along with disposable items like razors, silverware, cups, and food containers. Expanded Polystyrene is a different form of the material with a foam-like consistency used for packing materials, insulation, and disposable food containers.. I contacted James Hurt, Public Services Director for Grand Rapids, who indicated that since the Kent County Recycling Facility did not accept expanded polystyrene, the the city could not accept it either. Hurt was ...

Nanotoxicology has emerged as a discipline of a result of the revolution of nanotechnology. While nanotoxicology is in its infancy, there is a lack of toxicological data for nanoparticles, naturally occurring or commercially produced. The need for information regarding mechanisms associated with nanoparticle uptake by biological cells, as well as internalisation and accumulation of nanoparticles once penetrating cell membranes, is imperative. This project will focus on the internalisation studies of surface modified polystyrene nanoparticles. An in vitro lung model consisting of A549 (ATCC No: CRL185), a carcinogenic lung epithelial cell line, was employed to investigate the biocompatibility of nano scaled polystyrene particles in pulmonary systems. Biological effects of 40nm and 100nm carboxylated surface modified nanopolystyrene, 50nm and 100nm neutral nanopolystyrene and 60nm aminated nanopolystyrene were monitored. Prior to cellular studies, a full particle size characterisation was carried out
Adhesion is a crucial initial step in microbial biofilm formation. Firm attachment to a target surface subsequently ensures successful colonization and survival despite turbulent conditions. In the laboratory, polystyrene plates are commonly used in biofilm experiments and the washing/rinse steps before staining are critical for assaying biofilm viability. However, these rinse steps risk the removal (partially or entirely) of the formed biofilm, resulting in inconsistent results. The aim of the present study was to optimize conditions for firmer biofilms, less prone to disruption and thus significantly reducing well-to-well variability. Candida albicans SC5314 was used in five different polystyrene 96-well plates from four different manufacturers. Irrespective of how gently we performed the rinse, biofilms came off certain polystyrene plates more easily compared to others. Importantly, preconditioning the polystyrene surfaces with foetal bovine serum (FBS) had a negative impact on firm biofilm ...

Background Dibutyl phthalate (DBP) is predominantly used as a plasticizer inplastics to make them flexible. Extensive use of phthalates in both industrial processes and other consumer products has resulted in the ubiquitous presence of phthalates in the environment. In order to better determine the level of pollution in the environment and evaluate the potential adverse effects of exposure to DBP, immunoassay for DBP was developed. Methodology/Principal Findings A monoclonal antibody specific to DBP was produced from a stable hybridoma cell line generated by lymphocyte hybridoma technique. An indirect competitive enzyme-linked immunosorbent assay (icELISA) employing direct coating of hapten on polystyrene microtiter plates was established for the detection of DBP. Polystyrene surface was first oxidized by permanganate in dilute sulfuric acid to generate carboxyl groups. Then dibutyl 4-aminophthalate, which is an analogue of DBP, was covalently linked to the carboxyl groups of polystyrene surface with

Nanosphere lithography, an inexpensive and high throughput technique capable of producing nanostructure (below 100 nm feature size) arrays, relies on the formation of a monolayer of self-assembled nanospheres, followed by custom-etching to produce nanometre size features on large-area substrates. A theoretical model underpinning the self-ordering process by centrifugation is proposed to describe the interplay between the spin speed and solution concentration. The model describes the deposition of a dense and uniform monolayer by the implicit contribution of gravity, centrifugal force and surface tension, which can be accounted for using only the spin speed and the solid/liquid volume ratio. We demonstrate that the spin recipe for the monolayer formation can be represented as a pathway on a 2D phase plane. The model accounts for the ratio of polystyrene nanospheres (300 nm), water, methanol and surfactant in the solution, crucial for large area uniform and periodic monolayer deposition. The ...
Bio VI Surface functionalization of biological inert polymers, for example polypropylene and polystyrene, with material binding peptides facilitates an efficient immobilization of enzymes, bioactive peptides or antigens at ambient temperature in water. The developed Peptide Polymer evolution protocol (PePevo) is robust directed evolution protocol that enables to tailor polymer binding anchor peptides for efficient binding under application conditions. Key for a successful directed evolution campaign was to develop an epPCR protocol with a very high mutation frequency, 60 mutations per kb, to ensure sufficient diversity in the peptides LCI and Tachystatin A2. LCI and Tachystatin A2 were genetically fused to the reporter eGFP to quantify peptide binding on polypropylene and polystyrene surfaces by fluorescence analysis. PePevo was validated in two directed evolution campaigns for both peptides and polymers, LCI and polypropylene as well as Tachystatin A2 and Polystyrene. The nonionic surfactant ...

The local surface properties of polystyrene (PS) dishes incubated for 14 h with gram‐negative cells (Shewanella putrefaciens) were investigated by atomic force microscopy (AFM) in aqueous solutions at two pH values (4 and 10). The AFM images and force curves revealed the presence of a polymeric layer adsorbed onto the PS surfaces in acid media. In contrast, no evolution was observed in the case of basic media
The fabrication of cell sheets is a major requirement for bottom-up tissue engineering purposes (e.g. cell sheet engineering) and regenerative medicine. Employing thermoresponsive polymer coatings as tissue culture substrates allows for the mild, temperature-triggered detachment of intact cell sheets along with their extracellular matrix (ECM). It has been shown before that biocompatible, thermoresponsive poly(glycidyl ether) monolayers on gold substrates can be utilized to harvest confluent cell sheets by simply reducing the temperature to 20 °C. Herein, we report on the first poly(glycidyl ether)-based coating on an application-relevant tissue culture plastic substrate. We devised a simple, substrate geometry-independent method to functionalize polystyrene (PS) surfaces from dilute ethanolic solution via the physical adsorption process of a thermoresponsive poly(glycidyl ether) block-copolymer (PGE) bearing a short, hydrophobic, and photoreactive benzophenone (BP) anchor block. Subsequently, ...
Mueller matrices of dense aqueous suspensions of different concentrations are measured with a phase-modulated Mueller ellipsometer as a function of the scattering angle. Different concentrations of a solution containing 404-nm-diameter polystyrene latex spheres dispersed in water were prepared. Experimental results are compared with a three-dimensional Monte Carlo simulation of the propagation of photons with the cell geometry accounted for. The Fresnel laws and the Mie theory determine the changes in direction and polarization during the propagation of the photon. Excellent agreement over the whole angular range is found between experimental and simulated Mueller matrices.. © 2001 Optical Society of America. Full Article , PDF Article ...

Rapid Electrokinetic Patterning (REP) is an optoelectric technique for trapping and translating micro- and nanoparticles non-invasively. It uses a combination of laser-induced AC electrothermal flow and particle-electrode interactions in the presence of a uniform AC electric field. The trapping is governed by laser power, electric field strength, AC frequency and dielectric properties of the particle and the medium. A REP trap has an AC frequency, termed critical frequency, above which particles cannot be trapped. It is expected to be dependent on dielectric properties of the particle and the medium. However, we propose that the particle concentration and AC field strength also influence the critical frequency. In our experiments, we test 1 µm polystyrene microspheres in REP under the condition of three particle concentrations and two electric field strengths while keeping the laser power fixed at 25mW. We find that as the particle concentration increases, the critical frequency increases. Besides, by
Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS), commonly called Blue Board manufactured as foam continuous building insulation board used in walls, roofs, and foundations as thermal insulation and water barrier. This material is light blue in color and is owned and manufactured by The Dow Chemical Company.[1] In the United States and Canada, the colloquial use of the word styrofoam refers to another material that is usually white in color and made of expanded (not extruded) polystyrene foam (EPS). It is often used in disposable coffee cups and coolers, and as cushioning material in packaging.[1] The trademarked term is used generically although it is a different material from the extruded polystyrene used for Styrofoam insulation. The Styrofoam brand polystyrene foam, which is used for craft applications, can be identified by its roughness and the crunch it makes when cut.[citation needed] Additionally, it is moderately soluble in many organic solvents, ...

Alternative, non-electrochemistry-based technologies for continuous glucose monitoring are needed for eventual use in diabetes mellitus. As part of a programme investigating fluorescent glucose sensors, we have developed fibre-optic biosensors using glucose/galactose binding protein (GBP) labelled with the environmentally sensitive fluorophore, Badan. GBP-Badan was attached via an oligohistidine-tag to the surface of Ni-nitrilotriacetic acid (NTA)-functionalized agarose or polystyrene beads. Fluorescence lifetime increased in response to glucose, observed by fluorescence lifetime imaging microscopy of the GBP-Badan-beads. Either GBP-Badan agarose or polystyrene beads were loaded into a porous chamber at the end of a multimode optical fibre. Fluorescence lifetime responses were recorded using pulsed laser excitation, high speed photodiode detection and time-correlated single-photon counting. The maximal response was at 100 mM glucose with an apparent K(d) of 13 mM (agarose) and 20 mM (polystyrene), and

Great news from the west coast! Last week, the San Francisco County Board of Supervisors unanimously passed a ban on the sale of polystyrene foam. Foam packing, cups and mooring buoys will be prohibited starting January 1, 2017. This is a major win for the health of our ocean and marine life!. As you may already know, the problems associated with expanded polystyrene (foam) products is that they often fragment into small pieces once in the ocean, where fish, sea turtles or seabirds can mistakenly eat the tiny plastic bits. Nearly 425,000 foam cups, plates and food containers were removed from beaches by volunteers during the 2015 International Coastal Cleanup alone. And even more astounding are the more than 950,000 pieces of foam volunteers found on beaches around the globe during the 2015 Cleanup.. The ban in San Francisco is another step towards trash free seas! We continue to see dirty beaches and debris floating on the oceans surface. Thats why my colleagues and I are committed to ...
The Australian Packaging Covenant has recognised EPS as a priority waste stream and mandated to remove all packaging from landfill by 2025 to reduce this strain.. Businesses need to prepare for the packaging ban before they are caught out and left scrambling, said Chris Tangey, General Manager of Expanded Polystyrene recycler Ecycle Solutions.. South Australia has already implemented a landfill ban, with Victoria having confirmed that a similar ban will be introduced in the near future. It is only a matter of time before other states follow this lead.. The responsibility of recycling Expanded Polystyrene falls on businesses to drive change, said Tangey.. By starting with businesses, a large percentage of EPS waste will be recycled, prompting customers who receive goods to follow suit.. In the 2018/19 financial year, Ecycle Solutions helped 299 retail stores recycle their EPS waste. The volume of loose EPS waste collected from these stores equaled the volume that would fill the Melbourne ...

Sodium polystyrene sulfonate (SPS: Kayexalate®) is an ion-exchange resin used to treat hyperkalemia in patients with chronic kidney disease. It is known that this resin sometimes causes colonic necrosis and perforation, but there are few reports about small bowel necrosis associated with SPS. We herein report the case of a patient who developed SPS-induced small bowel necrosis, which was diagnosed based on the examination of a small bowel endoscopic biopsy specimen. The SPS-induced small bowel necrosis was resistant to conservative treatment including the cessation of SPS, and finally required surgical bowel resection ...

Nano-sized materials could find multiple applications in medical diagnosis and therapy. One main concern is that engineered nanoparticles, similar to combustion-derived nanoparticles, may cause adverse effects on human health by accumulation of entire particles or their degradation products. Chronic cytotoxicity must therefore be evaluated. In order to perform chronic cytotoxicity testing of plain polystyrene nanoparticles on the endothelial cell line EAhy 926, we established a microcarrier cell culture system for anchorage-dependent cells (BioLevitatorTM). Cells were cultured for four weeks and exposed to doses, which were not cytotoxic upon 24 hours of exposure. For comparison, these particles were also studied in regularly sub-cultured cells, a method that has traditionally been used to assess chronic cellular effects. Culturing on basal membrane coated microcarriers produced very high cell densities. Fluorescent particles were mainly localized in the lysosomes of the exposed cells. After ...
We present a low-cost, high-speed, retrofitted laser scanning module for microscopy. The cage-mounted system, with various available fiber-coupled sources, offers a real-time imaging alternative to costly commercial systems with capabilities for conventional or confocal reflectance and fluorescence applications as well as advanced laser scanning microscopy implementations. Reflectance images of a resolution target and confocal images of fluorescent polystyrene beads are presented for system characterization. Confocal fluorescence image stacks of T84 epithelial cancer cells are presented to demonstrate application to biological studies. This laser scanning module is a flexible, scalable, high-speed alternative to commercial laser scanning systems suitable for applications requiring a simple imaging tool and for teaching laboratories.. © 2005 Optical Society of America.

Abstract: A commercial and very hydrophobic styrene-divinylbenzene matrix, MCI GEL CHP20P, has been compared to octyl-Sepharose beads as support to immobilize three different enzymes: lipases from Thermomyces lanuginosus (TLL) and from Rhizomucor miehie (RML) and Lecitase Ultra, a commercial artificial phospholipase. The immobilization mechanism on both supports was similar: interfacial activation of the enzymes versus the hydrophobic surface of the supports. Immobilization rate and loading capacity is much higher using MCI GEL CHP20P compared to octyl-Sepharose (87.2 mg protein/g of support using TLL, 310 mg/g using RML and 180 mg/g using Lecitase Ultra). The thermal stability of all new preparations is much lower than that of the standard octyl-Sepharose immobilized preparations, while the opposite occurs when the inactivations were performed in the presence of organic co-solvents. Regarding the hydrolytic activities, the results were strongly dependent on the substrate and pH of measurement. ...

FlashPlate® is a white polystyrene microplate, designed for high-volume, homogeneous radiometric assays, based upon the principle of scintillation proximity. The interior of each well is permanently coated with a thin layer of polystyrene-based scintillant which provides a platform for non-separation assays using a variety of isotopes (e.g.,3H, 125I, 14C and 33P) without the addition of liquid scintillation cocktail. FlashPlate is available in both 96-well and 384-well formats.. ...
A majority of all biologically active proteins are glycosylated and various diseases have proven to correlate with alterations in protein glycosylation. Sensitive identification of different glycoprotein glycoforms is therefore of great diagnostic value. Here we describe a method with potential for glycoprotein profiling, based on lectins as capture probes immobilized on particulate substrates in the nm-range. The nanoparticles present high concentrations of attachment sites for specific ligands and cause minimal steric hindrance to binding. In the present model study the mannose-binding lectin ConA has been coupled to polystyrene nanoparticles via a poly(ethyleneoxide) linker which protects the protein conformation and activity and prevents unspecific protein adsorption. The ConA-coated particles are accommodated at different spots on the analytical surface via oligonucleotide linkage. This attachment, which relies on the hybridization of complementary oligonucleotides, allows firm fixation of ...

Ambient inhalable particulate matter acts as an efficient carrier of allergens allowing penetration deep into the distal airways. Epidemiological studies have shown an association between the increased incidence of asthma and levels of ambient particulate matter from air pollutants. Most experimental models investigating the pathogenesis of allergic asthma have used soluble allergens (sAgs) whereas knowledge is limited regarding the responses evoked by particulate allergens (pAgs). In this study, pathological responses to sAgs were compared with the same amount of allergens adsorbed on to the surface of polystyrene particles, in sensitised mice.. Regardless of allergen type, airways hyper-responsiveness and eosinophil infiltration were significantly greater with pAgs compared with sAgs. The response was blunted in mast cell (MC)-deficient mice suggesting that MCs are crucial in this response. MCs were able to distinguish between pAgs and sAgs. A fivefold greater MC IgE receptor-mediated response ...
